Circuit Resistance (per EN794 –1)
It is important to check the inspiratory and expiratory resistance specification of patient circuits used with the AVEA to
ensure they do not exceed the following limits when adding attachments or other components or subassemblies to the
breathing circuit.
NOTE
Refer to product labeling supplied with any accessory to be added to the breathing circuit for this information.
